Subject: usb: phy: mxs: use readl(), writel() instead of the _relaxed() versions
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b5a726b30436ab332aea4133bbfa0484d1c658b3;p=deliverable%2Flinux.git

usb: phy: mxs: use readl(), writel() instead of the _relaxed() versions

This patch converts the mxs-phy driver from readl_relaxed(), writel_relaxed()
to the plain readl(), writel() functions, which are available on all platforms.

This is done to enable compile time testing on non ARM platforms.
